Abstract
La presente invención se refiere a proceso de vaciado en esponja perdida y bajo presión de piezas metálicas, que comprende las siguientes etapas: establecer un modelo de la pieza que se va a vaciar, formado de una esponja de materia orgánica revestida de una película refractaria; sumergir dicho modelo en un molde formado de arena seca sin elasticidad; llenar el molde con el metal en el estado fundido para calentar el modelo; evacuar los vapores y residuos líquidos emitidos por el modelo; permitir al metal fundido solidificarse para obtener dicha pieza; aplicar en el molde antes que la fracción solidificada de metal rebase el 40 por ciento en peso, una presión isostática de valor máximo comprendida entre 0.5 y 1.5 MPa; el proceso se caracteriza porque la presión aumenta con la velocidad en función de la granulometria de la arena y de la profundidad de la inmersión del modelo generada rápida y temporalmente por la perdida de carga a traves del nviel de su interfase, esta superpresión alcanza un valor comprendido entre los dos límites y decrece posteriormente a medida que la presión aumenta despues para mantener la presión constante hasta que se complete la solidificación.
